7b alZw/zom it may concern:

- Be it known that I, JOHN Kmwrcz, a citizen of the United States, residing at Hyde Park, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to sewing machines.

and more particularly to method and construction whereby the handling of thread ends is improved.

More particularly the invention relates to sewing vmachines such as button hole sewing machines, wherein asuccession of comparatively short stitching operations are effected and in which the loose thread at the beginning and end of each seam is desired to be eliminated.

Among the objects of'the present invention are to generally improve the operation of sewing machines with respect to the manipulation of the thread ends, to increase the convenience of operation and to efi'e'cta saving of thread. v

other objects will appear in the 'hereinafter following description of an example or illustration in which the present invention is embodied.

To the attainmentof the objects referred to the present invention consists in the novel parts, devices. combinations and other features described or d sclosed in the accompanying description and drawings.

In the drawings, showing one embodiment of the present improvements, Figure 1 is a right hand elevation of a sufiicient portion of a buttonhole stitching machine to show the application of the present improvements, the various parts being shown in their initial or final position. Fig. 2 is a plan view of the work clam plate and the parts carried by it, the same having its right band edge towardthe observer and the parts being shown in the position taken by them during the stitching when the loose thread end is about to be cut off. Fig. 3 is a right elevation showing the same parts as in Fig. 2 and in the same position. Fig. 4 is a section taken on the plane 44 of Fig. 2. Fig. 5 is a front elevation showin the same parts as in Figs. 2 and 3 and in t 1e same position. Fig. 6 is a partial bottom lan view of the machine with its lefthand side toward the while the stitchilzig observer. Fig. 6 is a partial front elevation partly in section, taken on the plane 77 of Figs. 1 or 6. Fi 8 is a perspective view of the cam controlhng the mechanism more particularly constituting the present invention. Fig. 9 is a partial plan vieiv on enlarged scale showing the relation of the thread hook or holder, the grip plate and the cutter.

Many of the general machine parts are of well known type and need not be specifically described. In the present drawings the same are, for convenience, generally modeled as 1n my prior pending application, Serial No. 827,276. I will now refer in a general way to some of the usual buttonhole machine parts. The present invention being applied particularly to the manipulation of the upper thread, the under stitching mechanism and the under thread are, for convenience, omitted from the illustrations. The upper thread is indicated by the reference an and the work by the reference 3 The machine comprises a bed plate 10 which may be attached. to a suitable base. The bed plate 10 carries beneath it the cam casing 11 containing the main cam 12 indicated in dotted lines, this being mounted on a short vertical shaft and servingto o crate or control many .of the active parts 0? the machine, such as the cutter which cuts the buttonhole and the work clamp moving connections. Above the bed plate 10 is the overhanging machine arm 13. Mounted in the bed p ate so'as tobe horizontally movable therein is the clamp plate 14. It may slide forward and backward'for the regular feed purposes in stitching up and down the sides of the buttonhole and'may swing laterally to, assist the operation of stitching the two ends. The clamp plate let or its roughened portion 15 constitutes the lower of the two opposed zwork' clamp members, the upper member or clam 16 being, in the present iliustration, capa 1e of vertical opening and closing movements. Forthis purpose the.

upper clamp 16 is carried at the forward end 'ofa clamp carrying arm,17 by which arm also the clamp is actuated. In the usual manner the clamp may closed upon the work before the cutting of the buttonhole and may be there locked and held during the movements of the clamp proceeds, the clam finallybeing opene at the completion of a l of the. operations so be automatically as to permit the. work 66 thread gripping position being removed or shifted between the stitching of successive buttonholes. The e ve pointed vertically reciprocating upper needle 18 is carried at the lower end of a needle bar 19 slidably mounted in the overhanging arm 13. The upper needle will be reciprocated from the usual stitching shaft and wili be operated in harmony \\'i h the under stitching mechanism. lhe upper needle 18 may be eccentric to its carrier and the entire stitching mechanism above and below the bed plate may be oscillated or rotated during the stitching of the ends of the but.- tonholo so as to carry the over-edge stitches around the ends in a curved path. The upper thread a: may be controlled in an ordinary manner and it is shown, after passing from the usual tension and takeaip, engag ing with a certain thread controlling or measuring or releasing member 20 which is automatically shifted; from whence the thread passes into the upper hollow end of the needle bar 19 and to a light tension de vice 21 carried at the lower end of the needle bar and thence to the needle 18. lhe drawings show a projection 22 engaging with and serving to effect the forward and backward shifting movements ofthe clamp plate ll, the part 22 being actuated from the main cam 12.

Referring now more particularly to the new mechanisms involved in the present im' provement, they comprise generally a thread holding and cutting means preferably in volving a separate thread holding or gripping device 25 and a thread cutting device or knife 37, which parts may cooperate with a third member or plate 32 to assist their functions. These three parts and their fittings wi-ll be later described in detail. I will first explain in a general way the preferred functions and mode of operation of the parts.

The operation of a huttonhole stitching machinehaving the thread holding and cutting means hereof, may, for convenience, be substantially as follows: The operator, upon pressing the starting. lever, puts the main cam into operation and immediately the work clamp is closed upon the work and then a buttonhole slit is cut in the work held in the clamp. The clamp now stands in cutting position. It thereupon is'moved o'uickly forward to stitching position and preferably during such forward movement the slit will be stretched open by the automatic swinging apart of the two roughened under clamp members 15 in a well known manner. Then the clamp has been shifted forward to stitching position the stitching shaft is thrown into action by its clutch and stitching eom menoes; During'this time the thread cutter 37 stands in retracted or inoperative position while the thread holder 25 is in its holding the end of each buttonhole,

of the upper thread at a slight distance above and from the point on the work l'l' i ti the stitching is to couunence. The lli ltlug proceeds while the holder thus, ilu'eada-zul. After the lint ten thread cutter mow-s ll llilx the inward iron: its retract" ed position to engage and not (lose to the work the thread end held by the holdrr. This leaves a loose end of thread hold by the holder. The cutter then retracts again to inoperative position. The holder next moves from its thread gripping position outwardly to where it may dlsrharge the loose thread end in a position removed from the stitching point, and the holder may then give a little quick discharging movement to throw out the thread. Thereupon the thread holder returns from ,its discharge position to its gripping position. In the meanwhile stitching has been proceeding until the buttonholo is completed, upon which the stitching mechanism brought to a stop with the upper needle out of the work. Immediately after the completion of the last stitch the thread holder shifts inwardly from its thread gripping position to thread taking position, it reaching around and engaging the thread close to the work. The thread holder then returns with a portion of the thread to its thread gripping position, the thread manipulating device 20 at the top of the machine at this time allowing suflicient slack so that the thread holder may draw the thread laterally, as described. The thread holder then effects the gripping of the thread, for example, by coiipcration with the member or plate 32 and when so gripped the thread is held slightly stretched owing to the tension device 21 on the needle bar. At this pointin'the operations the thread cu'tter again shifts from its retracted position inwardly 'to engage and cut the thread close to the work, thus leaving the end of the needle thread held by the thread holder. These operations are performed instantaneously and as soon as completed the work clamp in the natural operations of the machine, shifts rearwardly from shifting to cutting position, and, during such stitching, opens to release the work; During this final period also the thread cutter will retract although its retraction need not be complete as ,it may continue at the commencement of the operation onthe succeeding buttonhole- Finally the entire machine comes to a stop with the parts in initial position. It will thus be seen that during the production of every buttonhole .the thread holder operates once while the thread cutter operates twice, and in such a way that the thread end is cut close'to the work, not only at the beginning but at the completion the very slight amount of loose thread that must. be allowed for between butto holes being thus'left in the st tche ti i and has continued l thread holder which, at the proper time, suitably discharges it.

Having indicated the'preferiied operation of the machine when constructed in accordance with the annexed illustrative drawings, I will describe in detail the structure and connectionsof the thread holder and cutter.

The thread holder or device 25 is in the form of a hook which facilitates its function of moving inward to the sewing point to reach around and engage the thread so as to pull the thread outwardly to where the holder may grip the thread by cooperation with the fixed plate or grip member 32. The thread cutter 37 may be in any suitable form whereby it may be moved inwardly to the stitching point to cut the thread close to the work. We thus have the three cooperating members, the thread holding hook 25, the thread cutting knife 37 and the rip plate 32 cooperating with the thread ho der. These three'cooperative members might be mounted in various modes so that they will occupy their proper operating positions during the manufacture of buttonholes. Preferably these members are located adjacent to and to one side of, for example to the right hand side of, the stitching point. For convenience for example, they may all be carried by the carrying arm 17 of the right hand upper clamp member 16. By this arrangement the parts are properly located,- yet in such a way as not to interfere with the stitching or clamp operations and, indeed, upon the opening of the clamp the members 25, 32

and 37 lift with the clamp, thus leaving the operator free to shift, insert or remove the work.

The details of the fittings of the thread holding hook 25 may be varied indefinitely.

It is shown as carried or formed at the extremity of a carrying arm 26, which is movable with respect to the clamp arm 17,*hav-.

-ing a pivot or screw 27 between the carrying arms 26 and 17, and the arm 26 having an operating extension 28, preferably located at the rear where it may cooperate with the cam actuated parts that control the thread holder. The thread holder, its carrying arm, and its operating extension are capable of oscillating from right to left between three positions. The normal or middle or thread gripping position is shown in full lines, Fig. 2, while the inward or thread engaging position and the outward or thread ischarging position are shown in dotted lines. and the operating extension 28 may be made non-integral as shown. Thus the former is capable of sliding in the latter, which permits adjustment of the precise position of the hook 25, the adjustment being made permanent by the set screw 29.

The swinging movement of the thread holder being substantially horizontal its The thread holder carrying arm 26' pivot screw 27 is shown vertical. The carrier 26, or, rather t, e extension 28 to which it is secured, is vided with a plate-like lug 30 provided wih an aperture surrounding the screw 27. A certain friction device shown in detail in cross section in Fig. 4 is interposed between the lug 30 and thepivot screw 27 for imposing a frictionupon the shifting movements 0 the thread holder so that it will tend to steadily hold any position into which it is adjusted, This friction device'com-prisesa leather or similar washe 31 between the lug or plate 30 and the head of the screw 27.

Referring next to the relatively station- 25 cooperates to grip the thread, this is seen to' be a horizontal, flat, plate-like member carried in the proper'position at the for ward end of its carrying arm 33 which, at its rear end, is rigidly secured to the clamp arm 17 by means of a screw 34 and the pivot screw 27 already referred to.

The thread cutter 37, like the thread holder and the grip plate, is carried at the forward end of an arm 38. The arm 38, like the thread holder arm, is capable of swinging and for this purpose is pivoted' on a screw 39 at the' upper side of the clamp arm 17. The cuttter arm 38 is provided with an operating extension 40 extending rearswing the extension 40 of the cutter arm to the left, that is from the observer, in Fig. 2,

so as to move the knife or cutter to retracted osition. The 'normal orretracted position is determined by a stop pin 42 engaged by the extension 40. Fig. 2 shows in full lines the retracted or normal position of the arm 40 and indotted lines the position' it will assume when the cutter is shifted in ward to cutting position.

.T he elements 25 to 42 thus far described, as comprised in the present improvement, are allshown carried upon the clamp 'arm 17 which, in turn, is carried upon the sliding clamp plate 14. It is hi hly desirable that a clamp plate be easily etachable and the present invention is-so embodied in the illustrated machine as to permit the detachment of the clamp plate without the need of effecting any-detachments or adjustments of the thread holding and cutting device ()n sliding forwardly out of place the clamp vplate l-l and all of the elements 25 to 42 shifting the and, the refore, the thread holder, betweeiiits three -positions. The

The main cam 12 already referred to, or the vertical shaft or sleeve carrying it, may have a downward extension in the form of a sleeve 52 and, for convenienhe, the cam 53,

which'controls the thread holder and thread cutter of the present invention, may be secured directly on the sleeve 52, as shown. The connections between the "cam 53 and the operatingextensions28 and 4.0 of the holder and cutter arms areshown in Figs. 1, 6 and'7, andthe cam53, detached and in perspective is shownin Fig. 8. Since, in the present embodiment of this invention the movements of the holder and cutter are not simultaneous, the cam 53 may have two separate actuating or cam surfaces, one for the th read holder and the other for the thread cutter.

The thread holder cam or surface 55 is shown as concentrically arranged at the underside of the cam or disk 53 and it is engaged by 'a follower 56 which rocks down .wa/rdly and upwardly according to the irregularities of the cam surface. The fol lower 56, is carried at the left extremity of a rock arm 57 fast upon a rock shaft and the rock shaft 58 at the other end di rectly carries 'the upwardly extending actuating lever 50, before referred to, which en ges the rear extension 28 of the thread holder carrying arm. Thus, any downward movement of the follower 56, caused by the cam surface. 55 shifts the lever 50 and the extension 28 to the left while any upward movement shifts them to the right. A spring i is shown tending to hold the follower 56 against the cam The cam or disk 52-} likewise has a cam surface 61, with connections for Controlling the thread cutter 37. Thus, it is engaged by the follower 62 which is located at the end of rock arm 63 fast on rock shaft 64, the rock shaft also carrying the upwardly extending actuating lever 51, which operates against the force of the spring 41 to force to the left the operating extension 40 of the cutter carrying arm. A spring 65 tends QhOld the follower 62 to the cam or surface-61.

The connections now having been de scribed, reference will be made to'the configuration or timing of the two cams 55 andating the cutter at a different point in the cycle of movements. The contour of the two cams and their cooperating action may he best described by referring to the differcut parts of the cam surface in consecutive I order in connection with the successive functions of the two cams.

Normally when the machine is idle the follower of cam 55 stands at the point 55 and the follower of cam 61 stands at the point 61 (see Fig. 8.) In this condition of the parts the thread holder is in its middle or normal osition while the thread cutter is substant ally at its normal or outward position, having retracted from its cutting posit'ion. The holder is gripping the end of the;

thread passing through the eye of the up' per needle.

After the machine is started and a slight revolution is effected of the main cam 12 and the cam disk 58, the follower of the cutter cam 61 arrives at the point 61 and the knife is, therefore, entirely retracted; the'follower of the holder cam 55'arriving at 55".

The operations of closing the clamp, cutting the button-hole slit, shifting the clamp forward from cutting to stitching position, starting the stitching and effecting the first few stitches. for example, seven or eight of them. are represented at Fig. 8 by the idle cam portions 61 to 61 and 55 to 55. respecti vcl y.

The cutter cam portions 61 and 61 next come into effect to cause the thread cutter to more in and to cut the thread and to more out respectively. The holder cam porly?- or) is shown in the cam which gives a little lillflil nm'emcnt to the 'th read holder assisting the discharge of the thread end and at 55 the holder again resumes normal position. In the meanwhile the thread cutter is idle through the corresponding positions 61", 61 and 61 The stitching having proceeded and the buttonhoie being completed. the holder cam portion 55 comes into efi'ect to shift the thread holder inward to engage the thread extending from the final stitch to the needle. The cam portion 55 restores .the thread holder to normal position at which it grips the thread against the grip plate 32. The thread is then somewhat under tension, as before explained. Next the cutter cam portion (51 comes into effect to move the cutter inward so as to cut the thread close to the work, and, before the parts finally come to a stop, the cam shifts so that the follower is at the point 61, with the cutter moved outwardly, while at the same time, the holder cam portion 55 has come around to its original position. It is duringthis final movement that the work clamp shifts back from'stitching to cutting position and opens, whereupon the machine stops.

Aside from the details of the thread holding and cutting means or device, it will be seen that broadly the present invention embodies the combination with stitching means and feeding means for the work, of a suitable holding and cutting means adapted to operate in a certain manner, namely, to initially hold the thread end while the seam is started and to out such thread end close to the work, thus leaving a short detached piece or fragment of thread held thereby,- and to discard the thread fragment so produced by releasing or otherwise removing it, and after the stitching is done, or at the end of the seam, to re-engage and hold the thread at a point between the work and the needle, and to out for the second time the held thread close to the work, thus at the completion of all operations leaving the thread end in a condition held by the holding and cutting means in readiness for the commencement of-another seam.

It will thus be seen that I have described a sewing machine embodying the invention and attaining the objects and advantages hereinbefore recited, and other advantages will be apparent to those skilled in the art. Since many matters of design, arrangement, detail, structure, and other features may be variously modified or altered without de parting from the novel principles involved, it is not intended to limit the present-invention to such features excepting in so far as the same are set forth in the appended claims.

It is hereby certified that in Letters Patent No. 1,188,944, granted June '27, 1016, upon the application of John Kiewicz, of Hyde Park, Massachusetts, for an improvement in Sewing-Machines, an error appears in the printed specification requiringcorrection as follows: Page 5, after line 47, insert the following paragraph:

Stated another way, it is novel with this invention to combine with the stitching, feeding and operating mechanisms of any sewing machine, a thread holder or holding means adapted and fitted to take the thread between the needle and work, a cutter or trimming means adapted and fitted to sewer the thread between the holder and work, and automatic controlling means timed to cause the operation of the holder andtrimmer so that after the completing of one seam or buttonhole and in the period between that time and the starting of the next seam, the holder takes the thread and thereupon the trimmer sewers it, and so that thereafter and after the starting of the next seam, the trimmer for a second time severs the held thread, leaving a thread fragment in the holder. By this improvement the work may be shifted before the start ofeach seam without drawing thread. Also the needle thread end is left held in the holder suitably for the start of a seam. The thread is never lost control of and perfect trimming is insured. The loose held fragment is easily withdrawn and relinquished by the holder, where it can be di posed of without littering up the new seam. The very minimum of thread is wasted between scams, namel'uv the small fragment left in the holder by the two cuttings;

and that the said Letters Pateht should be read with this correction therein that the same may conform to the record of the case in the Patent Office.
